PAM8620
15W STEREO CLASS-D AUDIO POWER AMPLIFIER WITH POWER LIMIT
Description
The PAM8620 is a 15W (per channel) stereo Class-D audio amplifier
which offers low THD+N (0.2%), low EMI and good PSRRd thus high-
quality sound reproduction.
The PAM8620 runs off of an 8V to 26V supply at much higher
efficiency than competitors’ Ics.
The PAM8620 only requires very few external components,
significantly saving cost and board space.
The PAM8620 is available in a QFN5x5-32L package.
